OIL-BURNING APPARATUS.

Specification of Letters Patent.

Application filed may 31, 1911.

To all whom it may concern: 7

Beit known that I, ARTHUR E. HAUCK, a citizen of the United States,residing at Brooklymin the county of Kings and State of New York, haveinvented certain new and useful Improvements in Oil Burning Apparatus,of which the following is a full, clear, and exact specification.

This invention relates to oil burning apparatus, and has especialreference to the burning of liquid fuels, such as kerosene, crude oil,etc., for heating purposes, such as in metallurgical and metal workingoperations, such as brazing, tire fitting, shrinking, etc. 1

I have herein shown and described a portable apparatus particularlyconstructed and adapted for use in applying and removing the tires oflocomotive and other wheels, but also adapted for various other uses.

As generally constructed, the apparatus embodies a truck carrying aliquid fuel reservoir, connected with a preliminaryvaporizer and partialburner, an extinguishing tube and a final burner, which latter is shownherein in the form of a flexible adjustable ring adapted to embrace thetire or other device to be heated by the heat produced by the finalburning ofthe fuel.

I provide, where a greater degree of heat is required, an auxiliary fuelsupply connected to the final burner, but passing through the primarycombustion chamber so that the heat therein can be utilized not only forvaporizing the fuel for the partial combustion but the auxiliary fuelfor the final burner as well.

The invention also consists in the various combinations of parts anddetails of construction as will be more fully, understood in connectionwith the description of the accompanying drawings, wherein Figure l is aside elevation of an apparatus embodying the invention; Fig. 2 an endelevation; Fig. 3 a detail view of a slightly modified partialcombustion chamber; Fig. 4 a detailed view of the auxiliary fuel nozzle;Fig. 5 a cross-section of the flexible burner, as adapted forheatingtires, etc.; and Fig. 6 is an end view of the partial burner.

1 represents a truck or platform having an upright standard 2, whichcarries an upper adjustable section 3, herein shown as adjust-able bymeans of afin 1 passing through poles 5 in the stander 2.

6 represents a liquid fuel tank which is provided with a pump 7 forproducing a pressure on the surface of the fuel, and a gage 8.

9 is a fuel outlet-pipe provided with a valve 10 and connected by pipe11 to a partial burner 13, which partial burner 13 is connected with anextinguishing pipe 1 1, and the latter to the final burner 15. The pipe11 is connected to a strainer 16, then to a valve 17 which controls theflow of oil both to the main supply pipe 18 and the auxiliary supplypipe 19, each of these pipes 18 and 19 being provided with check valves20 closing toward the tank, to prevent any back pressure from forcingliquid in pipes 18 or 19 back into the tank. The pipe 18 is formed intoa coil 21 which coil 21 is connected to a hollow casting 22 containingan oil passage23, and thence a pipe 24 leads backward to a forwardlyprojecting nozzle 25. This nozzle consists of a plug having a small holethrough which the fuel will issue in the form of gas or vapor, whichwill be ignited and burned in part within the perforated cylinder 26,which, as shown, is carried by casting 22 and incloses the coil 21. Thecasting 22 is attached to a head 27 by arms 28, which head 27 is carriedby the extinguishing pipe or chamber 14.

29 represents an oil pan adapted to contain a small quantity of oilwhich when ignited will heat the pipe 18, coil 21, casting 22 andvaporizes the oil therein so that it will issue from the nozzle 25 inthe form of gas and ignite itself, it being understood that the airpressure in thetank thus forces the flow of oil, valves 10 and 17 beingopen. The air supply is such that the blast of vaporized fuel issuing ata high velocity from the nozzle 25 in line with the extinguishingchamber 14 will not burn completely, but will be extinguished uponpassmg into pipe 14 through the head 27. There will thus be contained inthe chamber 14: a large volume of combustible gas, of which only a smallproportion ofthe original fuel supply has been burned, and this gas willbe forced by the blast through pipe 11 to the final burner 15 Ashereinshown, the final burner 15 com- Pl'ififis a flexible pipe made ofmetal hose or ointed sections, provided with holes around its innerperiphery and plugged ends 30 which may be clamped together as by achain 31 to embrace the tire of a wheel 32.

The burner 15 carries a series of supports 33 which contact with thewheel to be heated, and thereby form a combustion space between theperiphery of the wheel and the final burner 15.

34 is a shield of asbestos fastened to the inner periphery of the burner15 for protecting the burner tube from excessive heat, and alsodeflecting the heat inwardly toward the tire which is to be heated.Preferably, the asbestos 34 will have a metal face 35, suitable holesbeing provided as 37 where the gas is to issue. The final burner tube 15is connected preferably at an intermedi ate portion to the extinguishingtube 14.

'In some instances, itis desirable to secure additional he'at at thefinal burner over and above that supplied by the means just described,and this is accomplished by the auxiliary pipe 19 controlled by valve38,and having a coil 39 within the head 27, and then leading the heatedadditional fuel mixture by pipe 40 to oppositely extending nozzles 41(see Fig. 4). As shown in the detail of Fig. 4, these nozzles 41 consistof plugs having small passages or nozzles 42 similar to the nozzles 25,and an enlarged dirt or sediment chamber 43 for trapping any solidparticles which may pass through the pipe 40. It will be seen that theauxiliary fuel supply will be vaporized in coil 39 and pipe 40 by theheat from the primary partially consumed gases, and then upon issuingfrom the nozzles 42 mix with the other gases. In practice I have foundthat the gases from the nozzle 25 which-are extinguished in theextinguishing chamber 14 because of deficiency of air, will sometimesre-ignite upon issuing from the holes 37 of the final burner 15, byreason of their heat, but in case this reignition should not occur theycan be readily ignited. It will be understood that the fiow of oil willbe readily controlled by valves 17 and 38 to secure any desired degreeof heat at the final burner 15.

In Fig. 3, a slight modification is shown, in which the heating coil 21is dispensed with, and the oil is vaporized at a nozzle 45 by a blast ofcompressed air from a source 46, the nozzle 45 being inclosed within aperforated c linder 47, the fuel mixture being extinguis ied uponpassing into head 27 and extinguishing chamber 14 as heretoforedescribed, the other parts remaining-substantially the same.

For adjusting the height of the apparatus,

a lever 48 (Fig. 2). connected to the upper section of standard 3 andmounted on a fulcrum 49 may be employed.

It is thought that the construction and operation of the invention willbe fully understood from the foregoing description.

So far as I am aware, it has not heretofore been proposed to vaporizeliquid fuel by its own heat of combustion and to then extinguish theflame and burn the residue at a final burner, nor, so far as I am aware,has it been proposed to utilize the heat of the extinguished ases forvaporizing an auxiliary supply of fuel and simultaneously burning theresultant mixture at the final burners, for obtaining a high degree ofheat. It will be understood that the parts herein shown as especiallyadapted for heating tires are not the only form in which the inventionmay be applied, as the construction of the final burner will be adaptedfor the purposes in view, and various modifications and changes withinthe scope of the appended claims may be made without departure from theinvention.
